“Every now and then I’ll do a peel on my face just to get rid of the old skin and promote the new,” she said.

The 25-year-old just signed on as the new face of Myer and is one half of this year’s winning couple on The Block.Knowles and her partner Josh Barker became the show’s unlikely superstars, winning over viewers with their down-to-earth attitude.

They’ve also become low-key property moguls. The couple sold their winning house on The Block to comedian Dave Hughes for $3.067 million and their own home in Melbourne’s Coburg sold for $1.631 million.

Knowles regularly works as an underwear and swimwear model fronting campaigns for big brands.

She’s previously told news.com.au that she exercises five to six times a week to maintain her figure and is very strict with her diet, avoiding all processed foods, sugar and junk food.

“I am pretty strict about keeping healthy and making sure I’m not eating processed foods and sugars,” Knowles said last year.

During filming on The Block she tried to stick to her healthy regimen.

“I was really lucky to have my mum make food and bring us veggie and lentil soup and healthy quiches with lots of veggies,” Knowles said.

“Having healthy snacks on hand was really key for us, because you’re up at 4am saying, ‘I’m starving, what can I have to eat?’

“There’s a really good smoothie bar down the road and I was there getting green smoothies every morning.

“But you’re tired, you’re stressed, you’re angry. It’s a big whirlwind of emotions. Sometimes you do give in and say, ‘Give me a lolly or a chocolate’.”
